Description

Technical Field

[0001] This utility model relates to the field of laptop computer technology, and in particular to a fan assembly for a laptop computer. Background Technology

[0002] A laptop is a small, portable personal computer that typically has computing power comparable to a desktop computer. Its design focuses on balancing mobility and practicality. It is mostly clamshell-style and integrates components such as a display screen, keyboard, touchpad, and battery. In the early days, due to technological limitations, it was relatively large and had limited performance. However, with the development of microelectronics, battery technology, and lightweight materials, it has gradually become smaller, lighter, and has improved battery life. From its initial purpose as a portable device for professional fields, it has gradually become a mainstream computing tool that meets the diverse needs of personal office work, entertainment, and study, driving the transformation of personal computing from fixed scenarios to mobile scenarios. However, due to the compact internal space of laptops, the processor, graphics card, and other core components generate a lot of heat when running, which seriously affects performance and lifespan. Therefore, a special fan assembly for laptops is needed.

[0003] Chinese patent CN221485866U, published on August 6, 2024, discloses a fan assembly, a laptop bottom shell, and a laptop. By setting an installation opening on the laptop bottom shell that matches the shape of the fan assembly, the fan assembly is installed inside the laptop through the installation opening on the bottom shell. That is, external air can directly enter the fan channel from the air inlet on the top cover of the fan assembly. However, the fan assembly of this laptop only relies on mesh to filter the air entering the air. The mesh is easily blocked by large dust particles and is inconvenient to clean. It requires disassembling the entire fan assembly, resulting in high maintenance costs for users. At the same time, the single mesh structure lacks functional layers such as electrostatic adsorption or activated carbon, and cannot filter oil fumes, odors, and charged particles in the air. When used in complex environments, pollutants are easily corroded by internal components. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a fan assembly for a laptop computer, including a laptop computer 1, a mounting groove 2 at the bottom of the laptop computer 1, a mounting shell 3 inside the mounting groove 2, a cover plate 4 on the top of the mounting shell 3, an exhaust fan 5 inside the mounting shell 3, an air intake assembly 6 inside the mounting shell 3, and a mounting protection assembly 7 on the surface of the cover plate 4.

[0025] The protective assembly 7 includes a dustproof frame 701, which is mounted on the surface of the cover plate 4. A locking block 702 is connected to the side of the dustproof frame 701. A slot 703 is provided on the inner side of the cover plate 4. A fine filter plate 704, an activated carbon filter 705, an electrostatic filter plate 706, and a primary filter plate 707 are all installed inside the dustproof frame 701. Fixing holes 708 are provided inside both the slot 703 and the locking block 702, and screws are connected to the fixing holes 708. 709, a nut 710 is connected to the top of the screw 709, a telescopic tube 711 is connected inside the nut 710, a telescopic rod 712 is slidably connected inside the telescopic tube 711, a guide block 713 is connected to the bottom side of the telescopic rod 712, a guide groove 714 is opened on the inner side of the telescopic tube 711, a return spring 715 is connected to the outer side of the telescopic rod 712, a connecting block 716 is connected to the top of both the telescopic rod 712 and the return spring 715, an L-shaped locking plate 717 is connected to the side of the connecting block 716, a limit groove 718 is opened on the inner side of the locking block 702, and a protective component is installed. The setup involves first fixing the dustproof frame 701 to the surface of the cover plate 4 by sliding the locking block 702 and the locking groove 703. Then, a screw 709 is passed through the fixing hole 708, and the nut 710 is tightened for secondary fastening. During the tightening process, the nut 710 drives the telescopic tube 711 to move downward. The telescopic rod 712 slides vertically under the constraint of the guide block 713 and the guide groove 714, while simultaneously compressing the return spring 715. When the nut 710 is tightened to the correct position, under the elastic force of the return spring 715, the connecting block 716 drives the L-shaped locking plate 717 to engage with the limiting groove 718. A robust locking structure is formed to ensure a tight fit between the dustproof frame 701 and the cover plate 4, preventing air leakage. In the air filtration stage, outside air enters through the dustproof frame 701, first passing through the primary filter plate 707 to intercept hair, large dust particles, and other debris, then being filtered by the fine filter plate 704 to filter fine dust, and the electrostatic filter plate 706 using the principle of electrostatic adsorption to capture tiny particles and charged pollutants. The activated carbon filter 705 adsorbs odors and harmful gases. The clean air after four layers of filtration then enters the fan assembly, ensuring clean air inside the laptop and reducing the impact of dust accumulation on heat dissipation performance.

[0026] Furthermore, the mounting slot 2, mounting shell 3, and cover plate 4 are all provided with two identical sets. One set of mounting shell 3 houses the exhaust fan 5, while the other set houses the intake component 6. Through the arrangement of the mounting slot 2, mounting shell 3, and cover plate 4, the two sets of symmetrical structures construct independent and efficient air intake and exhaust channels, forming a complete heat dissipation airflow circulation system. The mounting slot 2 provides precise positioning and stable support for the mounting shell 3, ensuring that the fan component is firmly installed and avoiding shaking and noise during operation. The mounting shell 3 protects and guides the exhaust fan 5 and intake component 6, optimizing airflow direction and improving heat dissipation efficiency. The cover plate 4 not only seals the mounting shell 3, protecting the internal fan component from dust and debris, but also further filters the air through the installation of the protective component 7. At the same time, its flat surface fits snugly against the bottom of the laptop 1, ensuring the integrity and harmony of the overall appearance. This allows the fan component to enhance heat dissipation performance while also taking into account structural stability and aesthetics.

[0027] Furthermore, the air intake assembly 6 includes an intake fan 601, with an air outlet slot 602 on its side. A connecting plate 603 is connected to the top of the intake fan 601, and an air inlet 604 is formed on the surface of the connecting plate 603. A mounting bracket 605 is connected to the surface of the connecting plate 603, and a cooling pipe 606 is mounted on the surface of the mounting bracket 605. Through the configuration of the air intake assembly 6, the intake fan 601 generates suction after starting, and outside air enters the assembly through the air inlet 604 on the surface of the connecting plate 603. Multiple sets of air outlet slots 602 arranged in a cross shape can evenly disperse the intake air into the mounting housing 3, avoiding concentrated airflow that could lead to uneven local air pressure and ensuring the stability of airflow. High efficiency is achieved through the cooling pipe 606 on the mounting bracket 605, which plays a crucial role. The coolant inside the cooling pipe 606 is connected to the internal heat dissipation system of the laptop 1. When the coolant flows through the cooling pipe 606, it absorbs heat from the air outside the pipe, reducing the temperature of the air entering the mounting shell 3. The cooled air and the hot air exhausted by the exhaust fan 5 form an efficient heat exchange, greatly improving the heat dissipation effect of the laptop. The air intake assembly 6, through the coordinated operation of the intake fan 601, exhaust duct 602, air intake hole 604, mounting bracket 605 and cooling pipe 606, not only introduces sufficient cool air to the laptop, but also pre-cools the air, effectively enhancing the overall performance of the heat dissipation system.

[0028] Furthermore, the exhaust slots 602 are arranged in multiple sets on the side of the intake fan 601, and are distributed in a "+" shape with the center of the intake fan 601. Through the arrangement of the exhaust slots 602, the multiple sets of exhaust slots distributed in a "+" shape can evenly guide the air drawn in by the intake fan 601 to the surroundings, avoid the airflow concentration and turbulence, and ensure that the cool air efficiently and stably covers the heat-generating area inside the laptop, thereby improving the uniformity and effectiveness of heat dissipation.

[0029] Furthermore, multiple sets of air inlets 604 are provided on the surface of the connecting plate 603, and are distributed at equal intervals around the center of the connecting plate 603. Through the arrangement of the air inlets 604, the multiple sets of air inlets distributed at equal intervals around the center allow outside air to enter the air intake component 6 evenly from multiple directions, thereby expanding the air intake area, reducing air intake resistance, effectively improving air intake efficiency, ensuring a sufficient supply of cool air, and providing a good foundation for heat dissipation of the laptop.

[0030] Furthermore, the cooling pipe 606 is spirally distributed around the surface of the connecting plate 603, and the inside of the cooling pipe 606 is filled with coolant. The two ends of the cooling pipe 606 are respectively connected to the heat dissipation system inside the laptop 1. Through the arrangement of the cooling pipe 606, the spiral distribution increases the contact area between the coolant and the air, prolongs the contact time between the air and the cooling pipe 606, and allows the coolant to fully absorb the heat from the air, achieving deep cooling of the intake air, further enhancing the heat dissipation performance of the laptop and reducing the temperature of the internal components.

[0031] Furthermore, the dustproof frame 701 is installed on the surface of the cover plate 4 via the locking block 702 and the locking groove 703. The outer wall size of the locking block 702 matches the inner wall size of the locking groove 703. Through the setting of the locking block 702 and the locking groove 703, the precise matching size allows the dustproof frame 701 and the cover plate 4 to achieve a tight sliding locking connection. This facilitates the quick installation and removal of the dustproof frame 701, makes it easy to clean and replace the internal filter, and effectively prevents dust from entering from the connection point, ensuring the filtration effect and installation stability.

[0032] Furthermore, the fine filter plate 704 is located at the bottom of the inner wall of the dustproof frame 701, the activated carbon filter 705 is located above the fine filter plate 704, the electrostatic filter plate 706 is located above the activated carbon filter 705, and the primary filter plate 707 is located at the top of the inner wall of the dustproof frame 701. Through the arrangement of the fine filter plate 704, the activated carbon filter 705, the electrostatic filter plate 706, and the primary filter plate 707, a four-stage filtration structure is formed to create a graded filtration system. The primary filter plate 707 first intercepts large particulate impurities, the electrostatic filter plate 706 adsorbs small particles, the fine filter plate 704 filters fine dust, and the activated carbon filter 705 adsorbs harmful gases and odors, thus purifying the incoming air in all directions and protecting the inside of the laptop from dust and pollutants.

[0033] Furthermore, the telescopic rod 712 slides up and down inside the telescopic tube 711 via the guide block 713 and the guide groove 714. The outer wall size of the guide block 713 matches the inner wall size of the guide groove 714. Through the setting of the guide block 713 and the guide groove 714, the precisely matched size effectively constrains the sliding direction of the telescopic rod 712, preventing it from shifting or shaking during the telescopic process. This ensures that the telescopic rod 712 can stably drive the L-shaped card plate 717 to move, ensuring that the locking structure of the protective component 7 is stable and reliable, and improving the stability of the dustproof frame 701 after installation.

[0034] Furthermore, L-shaped clamping plates 717 are distributed in a cross shape on the side of the connecting block 716. The position of the L-shaped clamping plates 717 corresponds to the position of the limiting groove 718, and the outer wall size of the L-shaped clamping plates 717 matches the inner wall size of the limiting groove 718. Through the setting of the L-shaped clamping plates 717 and the limiting groove 718, the L-shaped clamping plates 717 and the limiting groove 718, which are distributed in a cross shape and are precisely matched, can firmly lock the dustproof frame 701 from multiple directions during installation, preventing it from loosening or falling off during the use of the laptop. At the same time, it provides good vibration resistance and ensures that the dustproof frame 701 always remains in a tight installation state.

[0035] Working principle: After the user turns on the laptop 1, the exhaust fan 5 and the intake assembly 6 start synchronously, forming a complete heat dissipation circulation system. The intake fan 601 in the intake assembly 6 draws in outside air through the air intake holes 604 on the surface of the connecting plate 603, and guides it evenly into the mounting shell 3 through the cross-shaped air outlet slots 602. During this process, the spirally wound cooling pipes 606 utilize the connectivity between the internal coolant and the laptop 1's heat dissipation system to pre-cool the air. The cooled air enters the laptop and absorbs heat from the CPU, GPU, and other heat-generating components. The heated air is then exhausted by the exhaust fan 5 to another set of mounting shells 3, and discharged into the external environment through the corresponding cover plate 4. During this period, the mounting protective assembly... Component 7 continues to function, with its four-stage filtration structure purifying the incoming air in stages, blocking dust and adsorbing pollutants to ensure the cleanliness of the air entering the laptop. Meanwhile, the multi-layered fixing structure, with the cooperation of the card block 702 and card slot 703, and the L-shaped card plate 717 and limiting slot 718, ensures the dustproof frame 701 is securely installed, preventing air leakage that could affect heat dissipation efficiency. Two sets of symmetrically distributed mounting slots 2, mounting shells 3, and cover plates 4 not only provide precise installation positioning and stable support for the fan assembly but also optimize airflow, enabling efficient exchange of hot and cold air. Ultimately, this achieves efficient heat dissipation for the laptop, effectively reducing internal temperature, ensuring stable operation of the device, and extending its lifespan. This completes the process of using a laptop fan assembly.
